Control of Synchronous Motors at low speed has been the topic of several studies for the last years. Due to the lower amplitude of Back-EMF voltage in lower speed, it is inappropriate to merely rely on induced voltages for position estimation. In this paper, a new double carrier PWM modulation is presented in which two carrier frequencies are utilized for two legs of the inverter. This proposed method rectify the need of powerful processors which decreases the cost of the electric drive system. Employing a non-linear control system and an automatic gain control, ensures the sensorless control of the motor for a wide range of speed.

Since the utilization of nonlinear loads such as power electronic converters have been increased and also because of the wide range of their usage and the creation of harmful harmonics, active and passive filters must be used to eliminate the effect of harmonics. In this paper, passive filters have been utilized because of fewer cost in terms of installation, maintenance and repair compared with active filters. The purpose of the current study is to find the optimal location of single-tuned passive filter and detect the size of its elements in distribution networks by a multi-objective approach. The objective functions include the reduction of network losses, initial investment cost and the improvement of the frequency response on critical buses. In this problem limitations such as buses voltage profile and harmonic distortion of the network are considered. To assess the proposed procedure, 33-bus IEEE test distribution network is used. As results the amount of network losses, buses profile voltage, and the network harmonic distortion are evaluated before and after the filtering and the accuracy of the method is evaluated too.

Direct torque control (DTC) scheme is one of the most appropriate methods to control of AC machines. This method has positive features such as fast response, simple structure and low dependence on motor parameters. However, the main problems in classic DTC method are variation of switching frequency and high ripple of flux and torque. These problems are approximately solved in the literature using advanced controllers and space vector modulation. Nevertheless, this paper presents a new DTC method using space vector modulation (DTC-SVM) in three-level cascaded H-bridge (CHB) converter, which has less switching losses than the conventional SVM (CSVM) methods. The proposed method uses switching sequences according to the reference voltage modulation index, which reduces the number of switching commutation and switching losses. Finally, the performance of the proposed method is presented through simulations in MATLAB/SIMULINK software.

This paper presents a novel modular-stator linear switched reluctance motor (MSLSRM) for elevator applications. The topology and its operating principle is illustrated and the magnetic equivalent circuit is derived for the aligned position. To attain the electromagnetic features of the motor, two dimensional and three dimensional finite element methods are employed. The static inductance and force profiles are obtained and the flux density distributions are given. Also, the dynamic operation of the introduced motor is performed. To demonstrate the positive sides of the suggested motor, a fair comparative study is done. To this end, two linear motors are considered and the static performance and dynamic waveforms of the three motors are compared. It is illustrated that the new motor has higher mean force and lower force ripple in comparison with the considered SRMs.

Classical transformers are the most important constituent of the power system and act as a passive interface between high voltage and low voltage systems. They have undesirable characteristics such as poor voltage regulation, large size/weight, sensitivity to harmonics, and poor power flow control. Solid-state Transformers (SSTs), are an emerging power electronics-based technology, sought to replace classical transformers after a century. SSTs are equivalent to a classical transformer with embedded desired functionalities. In this paper, three-phase AC-AC converter with capacitor at the DC-link is employed as power electronic interface in MV and LV side of the SST. Input-output feedback linearization (IOFL) controller is used to control the AC-AC based SST in two stages for controlling the external and internal states. AC-AC SST is linearized by the input-output feedback linearization technique where an internal dynamics is observed. IOFL is used to control the internal dynamics and second stage of the controller in the outer loop. Simulation studies are realized to confirm the applicability of IOFL controller and the control method.

The main contribution of this research is to present a modular hybrid reluctance motor (MHRM) for high-torque drive systems. The main sizes and parameters of the structure are presented. To obtain the main characteristics of the suggested HRM, a two dimensional finite element method (FEM) is used. The flux distributions at the alignment and unalignment of the rotor, flux linkage, and magneto-static torque profiles of the proposed topology are provided. In addition, the magnetic circuit model (MCM) of the introduced motor is derived, the reluctances of the machine are calculated, and the static features of the motor are attained from the MCM are compared with those of the FEM. The results are indicative of the fact that there is an acceptable discrepancy between the results of the FEM and MCM. Finally, it is shown that the HRM produces higher torque than the conventional SRM.

A multi-level inverter structure with capacitance switching based technology is proposed in the conducted study. The dominant feature of this inverter is that the obtained waveform of the output is similar to the sinusoidal wave. The purpose of this method is to apply the partial charging to obtain several voltage levels from each capacitor, which can diminish the quantity and capacity of the capacitors. To do this, only two capacitors are applied to produce 13- level in the suggested circuit. Moreover, the proposed framework is successfully fabricated along with evaluating the total harmonic distortion. In the following, a recommended switching method is introduced that is capable to heighten the derived voltage levels without increasing the quantity of elements. Simulation protocols are reported to validate the truthful operation of the suggested multi-level inverter.

Power converter design play an essential role in harvesting cheap and reliable electrical energy from solar energy. In the design of the converters, an appropriate trade-off between power converter output power quality and complexity should be made. Meanwhile, modular multilevel converters (MMC) are such a popular choice due to significant advantages like modularity, switching redundancy, the high number of voltage levels, lower output harmonics, elimination of expensive and huge output filters, etc. In this paper, a modified control strategy considering photovoltaic array structure for a high power MMC is presented. The proposed approach results in enormous faster dynamic and decoupled injected active and reactive power control. Also, using a single carrier modulation technique, and applying it to the capacitor voltage balancing algorithm, the capacitor voltage ripple is constrained to the allowed limits, which significantly decreases the circulation current. A 3MW 9-level MMC has been evaluated by MATLAB/Simulink to approve the operation of suggested modified current loop MMC controller.

In this paper, a novel non-isolated multi-input DC-DC converter (MIC) with high voltage gain has been presented. The presented topology comprises of simple high gain units. The main merits of the proposed topology are continuous current of input sources and possibility of using input sources of different voltage-current characteristics. Duty cycle of each unit can be specified independently and the amount of desired output voltage can be achieved. This topology has a simple switching pattern and the switching frequency can be selected high as well. The number of input units can be increased thus the stress of the switches is decreased as the duty ratio can be selected lower for each unit. The proposed topology is also appropriate for renewable energy sources’ applications and in order to validate the performance of the aforementioned merits, two units of multi-input DC-DC converter topology has been simulated in PSCAD/EMTDC software. Simulation results confirm the valid performance of the proposed topology.
